Abstract: 1473835 Crimped polyolefin filaments JAMES MACKIE & SONS Ltd 7 Aug 1974 [17 Aug 1973] 39022/73 Heading B5B Filaments of semi-crystalline polyolefins, e.g. pigmented polypropylene, are melt spun, rapidly and asymmetrically cooled, e.g. by an air current, formed into a tow or tows, heat treated at at least 100 C. so that a latent crimp of at least 2 crimps per cm. is produced, and subjected to two or more stages of drawing, the last stage being at at least 70 C. The heat treatment and first drawing stage may be carried out in a hot air or radiant oven, or by means of heated rollers or other surfaces, and the last drawing stage may be carried out in a water bath. The filaments may be formed into staple and spun into yarn, and used for making carpets. A further stage of heat treatment causes the latent crimp in the filaments to appear, and this treatment may be performed after formation of yarn or during the manufacture of the finished product, e.g. carpet, for instance when the backing is applied. A mechanical crimp may be applied to the filaments before the final heat treatment.

Filed: 1973-08-30
Abstract: Fat compositions which are suitable for the production of margarine with a high content of polyunsaturated fatty acids are obtained by mixing liquid vegetable oil which contains at least 40% by weight polyunsaturated fatty acids with 5-30% by weight hard fat. The hard fat used contains a) 25-60% by weight triglycerides, b) 35-70% by weight saturated fatty acids with 16-24 C atoms, c) 10-45% by weight mono-trans-unsaturated fatty acids with 16-24 C atoms, d) up to 25% by weight of fatty acids with 12-14 C atoms, where the total amount of component c) and component d) together is 15-45% by weight. The remainder comprising mono-cis-unsaturated fatty acids with 16-24 C atoms, poly-cis-unsaturated fatty acids with 16-24 C atoms, poly-trans-unsaturated fatty acids with 16-24 C atoms, unsaturated fatty acids with 12-14 C atoms and both saturated and unsaturated fatty acids with 2-10 C atoms amounts to 100 percent of saturated fatty acids with 16-24 C atoms + mono-trans-unsaturated fatty acids with 16-24 C atoms + saturated fatty acids with 12-14 C atoms. The resulting fat composition contains 0.2-5% by weight triglycerides which contain 3 saturated fatty acids with 16-24 C atoms. The margarine produced from these fat compositions is important from the dietetic viewpoint because of its high content of unsaturated fatty acids.

Title: Grounded aircraft trainers
IPC: G09B9/46
Filed: 1961-11-16
Abstract: 919,677. Grounded aircraft trainers; vehicles supported by gaseous cushions. DEL MAR ENGINEERING LABORATORIES. Nov. 16, 1961 [Feb. 16, 1961], No. 41124/61. Class 4. Apparatus for training in piloting of an aircraft which can hover, comprises such an aircraft coupled to a mobile base by means comprising rigid members jointed together so as to permit the attitude of the aircraft relative to the base to alter, whilst constraining the mobile base to follow all horizontal movements of the aircraft, the base being able to resist being turned over by the aircraft. In Fig. 1, a helicopter comprising a seat 10, main rotor 24, engine 12, tail rotor 27, and conventional collective and cylic pitch levers, throttle control, and pedals 32, is mounted by a ball joint 66 near its centre of gravity, on a support 35 slidable and rottable in a pedestal 58 on a base 34. The base may move on castors or, as , shown, may form a square plenum chamber supplied with compressed air by fans 52 driven by engines on the base, so that the whole apparatus is supported off the ground, and can move horizontally on application of cyclic pitch by the trainee. The helicopter can pitch and roll relative to the base, and complete rotation in azimuth and limited vertical movement are permitted by relative movement of support 35 and pedestal 58. Limit switches 132 and 133 on the pedestal operate lights 130, 131 in front of the trainee to show when the upward or downward limit of movement has been reached. The helicopter may be unable to lift the base clear of the ground cushion, or stops may be placed to limit the collective pitch or throttle setting to prevent take-off. Rotation in azimuth or vertical movement may be preventable by the insertion of pins in the pedestal, see Figs. 5 and 6 (not shown). Loss of air from the plenum chamber may be reduced as in Fig. 3, where the four side walls 40 of the chamber are hollow, and each contain a bar 42 having downwardly extending bristles 44 or skirts of plastic or elastomeric material deflectable by obstacles. Slots 45 in the bars work over bolts 45 through the walls, the bars being retractable into the walls on touching obstacles or the ground. Springs may urge the bars downwardly. Gas for the plenum chamber may be fed through the interior of support 35 from a compressor driven by engine 12, or from the engine exhaust. Castors 78 may be lowered by hand wheels 79 for ground manoeuvring when the gas supply to the plenum chamber is off. The base may be octagonal in plan, and be divided by radial partitions into sight separate plenum chambers. Outriggers 55, Fig. 1, with castors 56, prevent overturning of the base. Automatic stabilization signals in pitch, roll, and yaw channels may be added to the trainee's command signals, and the composition of these signals may be varied to alter the apparent control and stability characteristics of the helicopter as they appear to the trainee, see Figs. 8-10 (not shown).

Abstract: 1482126 Cathode-ray tube displays FUJI XEROX CO Ltd 23 Sept 1974 [25 Sept 1973] 41355/74 Heading H4T In a character display system in which the characters are composed of vectors, control words specifying the X and Y addresses of the start point, the length and the inclination of each vector together with a word specifying the number of vectors in each character are stored in addressable locations in a main memory (e.g. of a computer) from which they are read-out and employed to produce signals specifying the ON-OFF conditions of a marking member (e.g. the beam of a raster scanned cathode-ray display tube or a multiple stylus) which are required to display the characters, such signals being stored in a random access memory in the same configuration as the vectors occupy in the character and then read out in sequence and supplied to the display device. Fig. 1b shows in simplified vector form the Japanese character of Fig. la and Fig. 3 shows the corresponding control words for the various vectors a to s (Fig. 4) the angles (inclination) being coded as shown in Fig. 5 and the control word * indicating the number of vectors (17) in the character. These control words are prestored in addressable locations in a main memory 1 (Fig. 6) and when display is required an input character code, e.g. from a general purpose computer sharing memory 1, reads out the control words and supplies them via a buffer store 2 to a vector generator 5. The latter then generates blank-unblank signals which are stored in random access memory 4 in a configuration (see Fig. 8) corresponding to the character, i.e. the beam unblank signal, binary "1"s, represent successive portions of the vectors and the beam blank signals, binary "0"s, represent blank space as the character is reproduced within a 32 Î 32 dot display matrix as shown in Fig. 2, during successive horizontal line scans of the beam, the reproduction of the character by display means 56 commencing only when the complete character information has been stored in memory 4. Details of the vector generator 5 and of the control circuit 6A are given with reference to respective block circuit diagrams Fig. 6 and Fig. 9 neither shown.

In a door closer comprising a housing forming a reservoir for hydraulic fluid and containing a closing spring acting upon a check piston movable in a cylinder within the housing and linked with a spindle for connecting the closer to a door, a non-return valve is provided for permitting a free flow of fluid from the main portion of the reservoir into the cylinder during the opening movement of the door, and the closing movement is controlled by a pair of separate means one of which comprises a valve adjustable independently of the other means and arranged to permit a restricted flow during the whole of the closing movement and the other of which permits a restricted flow during an initial portion of the closing movement but is inoperative during the final portion of the movement. The first means is constructed so that the flow of fluid therethrough cannot be completely cut off. The drawings show a door closer adapted to be mounted in the lintel of a door frame and comprising a pair of closing springs 31 acting on pistons 20 movable in parallel cylinders 19 and linked by piston rods 40 to a pair of parallel plates 35, 36 provided with guide slots 37, 38. These slots receive corresponding shoulders 27, 28 formed on the spindle 24, and a cam 51 secured to the spindle moves in the space between the plates and co-operates with follower rollers 43, 44, 45 rotatable on shafts 48-50 mounted in the plates. Hold-open recesses 53 and hold-closed recesses 54 are formed in the cam surface. The cylinders 19 are connected by ports 80 to a bore 75 containing the first of the separate control means, which comprises a valve 70 screwed into the partition 18 between the cylinders to control the flow of fluid from the inner ends of the cylinders via a bore 79 to the main portion of the reservoir. A slight clearance between the valve stem 71 and the bore 75 prevents complete closure of the valve. The other control means comprises a tapered groove 65 in the wall of one of the cylinders which co-operates with the corresponding piston over the initial portion of the closing movement. In a modification the groove is replaced by a second valve similar to the valve 70 but spaced from the inner ends of the cylinders. A non-return valve 58 is provided in each of the pistons.
